i have a fixed 7440 bridge on my 91 Jackson Kip Winger Futura..
it's a great bridge.. think of it as individual bridges mounted on a plate..
if you feel like raising the string height at the bridge, you can just detune, move the saddle height, and retune..
you can also easily adjust for string spacing..
and, it's all tool steel.. no zinc/zamak.. they are solid..
it's a good choice right now.. Badass bridges are getting harder to get.. (Glen Quan is very sick right now, and it's a small business..) the prices have gone up on Badass bridges, too.. 100 bucks for one is not that unusual now, plus a wait..
the Kahler is cheaper, it's steel.. is very adjustable.. you can get it without a wait.. the 4 string bridge can add another saddle and become a narrow 5 bridge..
either way, you can't lose..
